oil measurement flowmeters

A quick guide to low-high viscosity oil measurement devices at KOBOLD.

Low-medium viscosity oil measurement flowmeters

 

EDM — Battery Powered Rate Meter and Totalizer

Our EDM series battery powered turbine flowmeter and totalizer measures water and other low-viscosity liquids. Its replaceable lithium battery powers an onboard flow rate meter/totalizer, allowing installation in virtually any location.

  • SS, Aluminum, PVDF, or Polyamide Bodies
  • Lithium Battery Powered (9000 Hr. Battery Life)
  • Compact and Portable
  • Ranges to 300 GPM
  • Rate and Totalizing Display
  • Optional Analog or Frequency Outputs

 

OVZ — Economical oval-gear flowmeter

The OVZ series oval-gear flowmeters offer the advantages of positive displacement technology at a rotameter price. Suitable for low-viscosity media ranging from hydraulic oils to light gear oils, OVZ eliminates problems associated with viscosity changes during operation.

  • Suitable for Oils from 10 to 800 cSt
  • Maintains Precision with Viscosity Change
  • Five Material Combinations Available
  • Easy to Maintain

 

DRZ piston flowmeter

The model DRZ positive-displacement flowmeter combines economy with high performance. Its single-piston design allows for precise volume measurement. The DRZ can measure any clean, free-flowing, low-to-medium viscosity liquid with lubricating properties ranging from diesel fuel to wax.

  • 1.6...110 GPH Flow Range
  • Accurate Measurements for Clean Lubricating Media
  • Economical Brass Construction

 

RCM - Direct Reading Flowmeters

Our Direct reading flowmeter model RCM is a great differential pressure device that is suitable for monitoring liquids and gases with low- to-medium viscosity and low solids content. A great choice for a flowmeter that is economical, compact, low maintenance, and durable.

  • Compact Design
  • Easy to Install on Horizontal or Vertical Pipes
  • Accuracy ± 3 % Full Scale
  • Rangeability 6 to 1
  • Flow Rates up to 3000 GPM Liquid or 20000 SCFM Gas
  • Optional Alarms and Output Signals

 

VKM - All-Metal Viscosity Compensating Flowmeter and Switch

Series VKM flowmeters and switches are unique offerings for low-to-medium viscosity media. These flowmeters use KOBOLD’s patented viscosity-compensation system, making them largely insensitive to density and viscosity changes while in operation. These meters are extremely versatile and can be used for just about any application.

  • ±5% Full Scale Accuracy
  • Viscosity Compensation to 540 cSt (No Scale Recalibration Necessary)
  • Max. Pressure: 3600 PSIG Brass/5000 PSIG SS
  • Density Compensation to 30 lb./ft3 (0.48 SG)
  • Direct Reading Scales
  • Installs In Any Position
  • Inline Connections

 

VKG - Viscosity Compensating Flowmeter with Switch

Like the VKM, the VKG series Flowmeter with Switch also uses KOBOLD’s patented viscosity-compensating system allowing it to become insensitive to viscosity and density changes during operation. It can be used for almost any application imaginable.

  • For Low-to-medium Viscosity Media
  • Viscosity-Compensated up to 540 cSt (No Scale Recalibration Necessary)
  • Density Compensated up to 30 lb/ft3
  • Direct Reading Oil Scale
  • Mounting Position Independent
  • Inline Connections for Easy Installation

 

High Viscosity oil measurement flowmeters

 

OME Helical Gear Flowmeter

The OME Series positive-displacement flowmeter provides the quiet, non-pulsating, low pressure-loss operation for which helical gears are renowned at a price comparable to oval-gear technology. It can measure non-abrasive, lubricating liquids with viscosity ranges of 1–5000 cSt.

  • ±0.3% of Flow Rate Accuracy
  • Advanced Helical-Gear Technology

Full-range viscosity oil measurement flowmeters

 

DON positive displacement flowmeter

Our DON series positive displacement flowmeters have an oval gear design that enables precise measurement of liquid flow over a very wide viscosity range. This device has become the meter of choice for lubricating/hydraulic oils, diesel fuels, chemicals, solvents, resins, and pastes.

  • Aluminum and Stainless Steel Bodies
  • Measures Liquids with Viscosities to 1,000,000 cPs (w/special cut gears)
  • Operating Pressures to 1,450 PSIG (model dependent)
  • Electronic Output Options Include Analog and Frequency Outputs, LCD Totalizers and Batch Controllers
  • Mechanical Totalizer (½" through 4" meters only)
  • Bi-directional Flow Sensing with Optional Quadrature Output

 

ZDM-positive displacement flowmeter

When your viscous flow metering application is particularly difficult or when the absolute in precision is a must, you’ll want to take a look at the ZDM Series positive-displacement flowmeter. Used to measure gasoline, hydraulic oils, inks, paints, polyurethane, pastes, creams, resins, and many others.

  • Viscosities up to 100,000 cSt
  • Accuracy ±0.3% of Flow
  • To 6500 PSIG Max. Pressure
  • Can Detect Flow Direction
